How to mimic Pivot Table or Categories in Number 3+

Perhaps you are already aware that Apple has cut many features from latest versions of Numbers and their other MS Office like products. One of the most popular features that has been removed from Numbers is called Categories. By activating Categories on a table you could aggregate data and summarize values see an overview of what matters to you. Recently I was working on a list of values and since the list was not bigger than what Numbers can handle and I didn’t need the speed and power of Microsoft Excel. I though I will give Numbers a try. I still like the fact that you have a free canvas in Numbers that allows you to put put many tables independent from each other in one page. I think it is the only advantage of Numbers to its alternatives. Otherwise with just a few dollars per months you could have access to the latest version of Microsoft Office regardless of your OS or even directly in your browser plus Microsoft gives you a terabyte of online storage! OK, let’s get back to work before I change your mind 😉

Let’s start with an example like the following.

A B
1 Category Amount
2 Blue 11.20
3 Red 15.89
4 Red 10.30
5 Orange 32.12
6 Green 15.39
7 Blue 10.18
8 Green 24.76
9 Green 89.31
10 Orange 8.75
11 Blue 15.28

The first column is just containing the order of each row, the second indicates the category of each row. This could be anything like category of expenses in an expense report. It is actually the column that we are going to aggregate. The third column contains the values. It could be the amount of each expense for example.

Now, let’s say you want to aggregate it to the following table. But you want Numbers to do it for you so each time a series of row is added to the table you don’t need to calculate everything manually.

Category Sum
Blue 36.66
Red 26.19
Orange 40.87
Green 129.46

Since I want to do the aggregation in the same table, I need to find a way to detect distinct categories. Then per each category I need to calculate and display the sum of each category in front of it. If I display only the first occurrence of each category and hide other occurrences the problem would be solved. Let’s split the problem to smaller pieces as usual. Now the first question would be how do we find distinct categories?

Step 1 – Detecting distinct categories

Let’s add a new column called “Test” then put the following formula in the first cell of the column below the header: =COUNTIF(A$1:A1,A2) in other words you need to put it in C2 cell. Now click at the bottom of the cell’s rectangle and drag it to the bottom of the table. This will fill remaining cells of the column. The result will be the following table.

A B C
1 Category Amount Test
2 Blue 11.20 0
3 Red 15.89 0
4 Red 10.30 1
5 Orange 32.12 0
6 Green 15.39 0
7 Blue 10.18 1
8 Green 24.76 1
9 Green 89.31 2
10 Orange 8.75 1
11 Blue 15.28 2

As you can see, you only get zeros for the first occurrence of each category and that means we can detect them with an IF. Now, let’s put the following formula in cell C2 instead: =IF(COUNTIF(A$1:A1,A2)=0,"*","") and as before drag the corner of the cell until the bottom of the table which will give us the following result.

A B C
1 Category Amount Test
2 Blue 11.20 *
3 Red 15.89 *
4 Red 10.30
5 Orange 32.12 *
6 Green 15.39 *
7 Blue 10.18
8 Green 24.76
9 Green 89.31
10 Orange 8.75
11 Blue 15.28

Now for first occurrence of each category we are displaying “*” in column C.It means that we are able to detect the first occurrence of each category and display an arbitrary text in it. What about displaying SUM of each category there. This would be the final solution.

My final solution

In this step we are going to replace the “*” in the formula with SUMIF(Category,C2,Amount) this way the SUM of each category will be calculate in front of each occurrence of that category. All you have to do is to put the following formula in C2, then drag the bottom-right corner of the cell until the bottom of the column.
=IF(COUNTIF(C$1:C1,C2)=0,SUMIF(Category,A2,Amount),””)
The resulting table will be similar to the following. I just renamed the Test column to “Total per category”. You can use formatting to distinguish the aggregate row or even hide other rows if you like.

A B C
1 Category Amount Total per category
2 Blue 11.20 36.66
3 Red 15.89 26.19
4 Red 10.30
5 Orange 32.12 40.87
6 Green 15.39 129.46
7 Blue 10.18
8 Green 24.76
9 Green 89.31
10 Orange 8.75
11 Blue 15.28

How to warm-up SharePoint or other web applications and WCF (SOAP) services with PowerShell

There are many reasons you might want to warm-up a web application occasionally. It can be after a fresh deployment or on a regular basis after recycling application pools. Some times you might also need to warm-up SOAP services without going through front-end.

It might seems to be any easy task specially if you have PowerShell 3.0 or higher on your servers, but after Googling a while and reviewing some of the top hits I discovered that each solution is missing a part. Some only work in a single server scenario and some has forgotten that each HTTP response might contain links to scripts and images that we need to download and finally I could not find anything for SOAP services that just works. Long story short I decided to put together a simple script that just works and is easy to change to everyone’s needs.

Please note that my only assumption is you have PowerShell 3.0+ in your servers.

Currently the script takes care of the following tasks, but I will most likely improve it to cover other useful scenarios.

  • Calling SOAP operations and sending parameters and custom headers
  • Calling front-end URIs and downloading scripts and images that are local to the front-end
  • Logging to a configurable folder and file name
  • Cleaning up old log files

Currently, I have the following points in mind to improve the script.

  • Put configuration in a different file.
  • Improve function definitions (named and typed parameters and description).
  • Default values for parameters when it makes sense (e.g. log folder can be the current folder).
  • Support REST services.

I’m open to any suggestion and feature request. Please let me know if you found it useful or if have got something wrong.
